The truth inherent in the title of this episode is vividly illustrated when the Ricardos sell their old washing machine to the Mertzes. The machine immediately malfunctions, whereupon Fred (William Frawley) and Ethel (Vivian Vance) demand that Lucy (Lucille Ball) and Ricky (Desi Arnaz) cancel the bill of sale, which amounts to 35 dollars. Lucy and Ricky refuse, insisting that since the Mertzes now own the washer, they are obliged to pay up. Not one but two zany slapstick set pieces ensue, concluding with a memorable climactic struggle on a second-story porch. This was the final episode of I Love Lucy's second season. ~ Rovi
